Just one question. Can i apply for product based company if currently i am in service based company

@Akshay Saini Debouncing will be suited for shooter games because user can stop shooting at any time, regardless of interval you have set and he can fire at any time so.. we should allow player to fire shot at any time unlike throttling fixed synchronous intervals shots will be delayed if your fire is not in sync with throttle intervals. My implementation would be the inverse of debouncing like count time in ms after any shot and then allow next shot after 200 ms for a pistol, i.e. block for 200ms whenever fired!!

[@robinsoni4778]

Hi @Akshay Saini, The Right words to explain this would be - Debouncing: Needed when we want to run the function after the user has stopped interacting for at least given limit time, Throttling: When requirement demands to run the function with the gap of limit time b/w two consecutive function call while user's interaction. I have deduced it after checking your code for both debouncing and throttling, please let me know if my interpretation is wrong. Thanks for the nice explanation.

[@AhmAsaduzzaman]

Throttling: Baby: Mom give me a piece of chocolate cake Mom: No you can get one, only after 1 hour (baby wont get a piece of cake no matter how many times she asked, but only after each hour) Debouncing: Baby: Mom give me a piece of chocolate cake, . . .Mom give me a piece of chocolate cake ... mom give me ... Mom: No, You will get a piece of cake only after 1 hour from LAST time you asked for one. 😃

[@akshaymarch7]

Hahaha, great example! 😅

[@MythicEcho]

Thanks for this analogy, now i can remember this topic for lifetime.

[@rajeshbudamgunta1491]

Debouncing: mom gives chocolate cake if time limit between two successive pleadings from baby greater than 15 mins

[@stanymadanu817]

Debouncing: mom gives chocolate cake to child only if the baby stop asking and then asks after 1hr. make sense i think 🤔

[@stanymadanu817]

here waiting period is important instead of multiple requests in debouncing

[@deepakchandani5237]

from JS engine's perspective throttling: I am working on something which might take x milliseconds, so don't disturb me for next x milliseconds debouncing: first you finish your action (typing, clicking) & then after x milliseconds I will fetch the required data

[@popop72276]

[@tambolaking5383]

I watch a lot of tutorials on youtube. Your topics are one of the most productive watch.

absolute genius, sir the way you explain concept is just incredible.

[@abhinavkumar7309]

Awesome! Shooting game example MG and pistol. Now I will never forget debouncing and throttling.

[@MS-nh7zj]

You are GOAT . keep making more videos , debouncing and throttling with ui and code also if you get free time . Thanks .

[@vikassharma5800]

To differentiate between Debouncing and Throttling, shooting game example was great. after that it gets crystal clear thank you Akshay

[@AbhishekGupta-nn3yu]

Hats off for explaining concepts in a very simple but effective way.. Thank you

[@gargipareek6890]

Very well explained. Throttling and debouncing sounds so easy now.

[@SHIVAMPANDEYSJTG]

Now I feel like I need to go through all of your videos 😂 to watch all the stuff ! Seriously Thank you!

[@SHIVAMPANDEYSJTG]

Well I am quite new to webdev, just 2-3 months still learning things. I still remember when I was thinking how to verify username is valid or not the first thing that came up to my mind was it would take so many API calls and is not efficient. Then I dropped the idea of implementing it but this video makes such a great sense. I had not heard of this term before and didn't had idea about it. I just saw it and thought here is something new to learn. You solved my problem in such an easy way. Thank You!

[@vivekmodi3165]

Both the concepts are very well explained with examples otherwise it would be difficult to understand. Thanks sir good explanation.

[@AdnanAli-cp9hk]

What an amazing explanation, and what a smooth way of explaining such complicated topics!

why dont you create playlist of react and angular? Your teaching skills are very good and easy to understand

Good job bro.. you are explaining it very well. Just a suggestion, when you are referring to your previous videos please do also provide its link in the (i) icon... It's very handy to you know just click and watch that video. Thank you

[@vikramsingla8590]

Clappings!! I would say. such a smooth explanation along with examples.

[@utkarshkandpal5960]

A debounced function may starve but a throttled function would never.

[@VijayKumar-zx5bm]

+one more to add. Sometimes in throttling, the final function call may not be happen whereas it would happen for debouncing. Eg Consider the situation of search bar, where on typing a key an API call is fired . Let the duration for throttling / debouncing be 3sec and say we are just searching string AI . In this case if the second key press (which in our case is key I ) is within 3 sec, then the search event won't be fired in Throttling whereas in Deboucing the search will be fired after 3 sec with AI as the string in the API call .

[@sahilGupta217]

@@VijayKumar-zx5bm Is it because there was no key pressed after ' I ' in case of Throttling that the API call will not be there?

[@sahilGupta217]

​@@VijayKumar-zx5bm Is this because we do not have any other key presses after ' I ' is pressed in case of throttling that the API will not be hit?

[@jayjani740]

@@sahilGupta217 That is why sometimes, we have to press "space" (at last) in order to search. I have experienced this somewhere sometine. If I am wrong, please corrcet me on my first statement. Thanks :)

[@AmiMish0909]

That gun and first person shooter example is lit 💖💖💖

[@bharatkumar-be9ki]

Awesome explanation. Couldn't have asked for a better video.

[@dominicvictor3940]

Shooting game analogy: Deboucing: When the user clicks on the shoot button 10 times (Number of Bullets) Reload the gun for more shooting. Throttle: When the user clicks on the shoot button, bullets runs out, but going to have to wait for the interval before it reloads by itsself

[@evergreen7781]

I recently gave an Interview, where I was asked not only to implement Debouncing but write test cases for it, also write a function to test your debounce function.

[@developerflaviant9894]

Bhai bohat research ki he tumne stackoverflow etc.. The way you teach is awesome. Good to know that you are from dehradun :) Keet it up and also it would be glad if you make video on react js

Hahaha 🤣

[@waytofar6554]

Explained very nicely!! Finally got to differentiate between these two :)

[@shayvajda]

Enjoying your videos! Do you mind doing a design question in vanilla js? (like writing a plugin for star rating) I'm not sure what is the best approach for a self contained plugin without a frameworks like react etc. Other than that, it really seems like you're enjoying yourself in these interviews!

[@codewithdjdev]

In simple terms: Debouncing delays the execution of a function until there's a pause, typically after a certain period of inactivity. Throttling limits the rate at which a function can be called, ensuring it's not executed too frequently.

[@tambolaking5383]

I think to put it together, in cases where user waits after action we use debouncing and in cases where user wants result during action, we implement throttling.

[@vinothkumarv9722]

Vinoth love akshay : Wow super awesome bro i will implement this feature to my current project as well as.

i bet you guys resized your player screen while watching this on his resizing example.. hehehe,, Excellent explanation here sir, keep it up, more power and happy coding =)

[@jayjani740]

Hi Akshay, Thanks for making video. My Question: Please generalize which concepts out of two can be used in what kind of scenarios?

[@RahulSoni11]

Very well explained. 👍👌

[@shubhammeshram2944]

Good explanation.

[@AdnanAli-cp9hk]

Visualizing the Difference Throttling: Imagine you are trying to listen to someone talk in a noisy room. You decide to check for new sounds only every 200 milliseconds. You might miss some details, but you get a general idea without being overwhelmed. Debouncing: Imagine waiting for a pause in the conversation to respond. You will only start talking after the person has been silent for 200 milliseconds, ensuring you don't interrupt them and respond only when they are finished.

[@shantanu_kumar]

Akshay, absolutely in love with your channel and your posts on Linkedin! :) Had a small doubt, would be great if you could help me with it! In the interview process for Frontend Engineers (FEE2 at Amazon in particular), is the system design part of the interview the same as the system design for WDE2/SDE2 roles? As in, since FE engineers are confined to the frontend, will the system design be related to frontend itself (scaling frontend, design systems, etc) OR will it be along the line of designing Dropbox or URL shortener, etc.?

Debouncing and throttling in one line. Debouncing - Only call the function when the difference between the last and current events exceeds the limit. Throttling - Only call the function when the difference between the last and current functions exceeds the limit.

[@hussaingagan9196]

Debouncing: In debouncing the event function WILL be called after the delay Throttling: In throttling the event function CAN only be called after the delay and any intermediate event fired will be ignored, only the event fired after the delay will be called

Hi Akshay Can you please make a video on the callback function wrapper(Interceptor) concept. Example: one callback API function already exists => getUsersList(_str, CB), you don't have access to CB, and the API function not returning anything(undefined), How can we introduce a wrapper on API, what data is it taking?
